RFID uses radio signals to read information from tags attached to products or other objects.
How it works in retail
Retailers can use tagged merchandise to support inventory counts, item tracking and stock visibility. Compatible tags, readers, software and operating procedures work together.
A retail example
An associate uses a handheld reader to count tagged garments on a rack without scanning each printed barcode individually.
What to keep in mind
Read performance depends on tag placement, materials and the environment. RFID data still needs reliable links to item records and inventory processes.
